Effects of Intraoperative Nitrous Oxide on Postoperative Pain for Patients With Current Opioid Treatment After Vertebroplasty.

Institut Bergonié·interventional·Posted Sep 21, 2005·Updated Sep 9, 2025

In Brief

A Phase 2 clinical trial evaluating Air and Protox for Chronic Pain. Completed, enrolled 39 participants across 1 site.

Detailed Summary

Peroperative opioids are known to induce N-Methyl-D-Aspartate dependent enhancement of postoperative hyperalgesia. For patients with current opioid treatment, these phenomena could be exagerated and could produce greater postoperative opioid consumption and higher pain score. Since Nitrous oxide has anti- N-Methyl-D-Aspartate properties, the aim of this study was to evaluate, in patients with current opioid treatment, the effects of peroperative Nitous oxide on postoperative opioid consumption and pain score, after vertebroplasty.

Interventions

Airprocedure

Patients undergo long-term morphine treatment and vertebral cementoplasty. During the procedure, patients are ventilated with a mixture of air and oxygen.

Protoxprocedure

Patients undergo long-term morphine treatment and vertebral cementoplasty. During the procedure, patients are ventilated with a mixture of oxygen and nitrous oxide.
